1:9-15 There is a great deal plotted against the Lord by the gates of hell, and against his kingdom in the world; but it will prove in vain. With some sinners God makes quick despatch; and one way or other, he will make an utter end of all his enemies. Though they are quiet, and many very secure, and not in fear, they shall be cut down as grass and corn, when the destroying angel passes through. God would hereby work great deliverance for his own people. But those who make themselves vile by scandalous sins, God will make vile by shameful punishments. The tidings of this great deliverance shall be welcomed with abundant joy. These words are applied to the great redemption wrought out by our Lord Jesus and the everlasting gospel, Ro 10:15. Christ's ministers are messengers of good tidings, that preach peace by Jesus Christ. How welcome to those who see their misery and danger by sin! And the promise they made in the day of trouble must be made good. Let us be thankful for God's ordinances, and gladly attend them. Let us look forward with cheerful hope to a world where the wicked never can enter, and sin and temptation will no more be known.
15. This verse is joined in the Hebrew text to the second chapter. It is nearly the same as Isa 52:7, referring to the similar deliverance from Babylon.
him that bringeth good tidings—announcing the overthrow of Sennacherib and deliverance of Jerusalem. The "mountains" are those round Jerusalem, on which Sennacherib's host had so lately encamped, preventing Judah from keeping her "feasts," but on which messengers now speed to Jerusalem, publishing his overthrow with a loud voice where lately they durst not have opened their mouths. A type of the far more glorious spiritual deliverance of God's people from Satan by Messiah, heralded by ministers of the Gospel (Ro 10:15).
perform thy vows—which thou didst promise if God would deliver thee from the Assyrian.
the wicked—literally, "Belial"; the same as the "counsellor of Belial" (Na 1:11, Margin); namely, Sennacherib.
